If the FCC was subject to multiple DDoS attacks that affected input in the Open Internet comment docket, leading House Democrats say that raises questions about the FCC’s cybersecurity preparedness that need answers.

That came in letters to the FCC and National Cybersecurity and Communications Integration Center.

“We ask you to examine these serious problems and irregularities that raise doubts about the fairness, and perhaps even the legitimacy, of the FCC’s process in its net neutrality proceeding,” the Democratic legislators said. “Giving the public an opportunity to comment in an open proceeding such as this one is crucial – so that the FCC can consider the full impact of its proposals, and treat everyone who would be affected fairly.”

Democratic Sens. Ron Wyden of Oregon and Brian Schatz of Hawaii had asked FCC Chairnman Ajit Pai for an explanation of the attacks. But the response—that they were “non-traditional” attaocks–only created new questions, the letters to the FCC and NCCIC said.

That includes:

•”What ‘additional solutions’ is the FCC pursuing to ‘further protect the system,’ as was mentioned in the FCC’s response?

•”According to the FCC, the alleged cyberattacks blocked ‘new human visitors … from visiting the comment filing system.’ Yet, the FCC, consulting with the FBI, determined that ‘the attack did not rise to the level of a major incident that would trigger further FBI involvement.’ What analysis did the FCC and the FBI conduct to determine that this was not a ‘major incident?’

•”What specific ‘hardware resources’ will the FCC commit to accommodate people attempting to file comments during high-profile proceedings? Does the FCC have sufficient resources for that purpose?

•”Is the FCC making alternative ways available for members of the public to file comments in the net neutrality proceeding?”
